How do I check if a variable is of array type?


If you want to check that you are dealing with an array and not a string, then you simply use is_array, like so:

<?php
$array 
= (1,2,3);
if(
is_array($array)) { echo "Look, an array"; } else { echo "You might be stringing me along"; }
//Look, an array
?>

Why would this function ever be useful?

It is useful precisely when you want to know whether you are dealing with an array or not, as the name suggests! This is useful because clearly you will want to treat the contents of an array differently to, for instance, a string.
